It provides employees with round-the-clock access to their pay data, so you can enjoy the convenience of accessing your payslips, P60s, P11Ds and uploaded iPayview documents via your smartphone whilst on the go. In order to use the mobile application, you must be connected to the internet and have an iPayview account. If you are not yet registered, you can do this quickly and easily via the existing web application. Key features of the mobile application include: • View current and historic payslips: The mobile application displays all current and historic payslip data that is available in the web application; • View year end documents: The mobile application displays all P60 and P11D document data that is available in the web application; • Export documents to PDF: This feature can be used with other applications or for simply storing and printing your documents; • Biometrics: This feature will allow you to use either fingerprint or face recognition to log in to the application. • Two Factor Authentication: This feature will provide you with an additional level of security when accessing information on the mobile application; • Day / Night Mode: This function provides you with the option to select either mode in line with your system preferences; At CGI, the protection of personal data is of the utmost importance. The iPayview app delivers information using the same secure API as its existing web-based counterpart, which already provides pay information to thousands of users worldwide. The app transmits all data using our own secure API to the end user’s device and utilises two-factor authentication to prevent unauthorised access from a user’s device. An additional client code, unique to each organisation, is required when logging on.

Verdict

The call

The clearest difference is monetization model: iPayview at free against ESi Centro's paid. iPayview also leads on review sentiment (40% vs 17%) and iOS requirement (13.0 vs 15.1). ESi Centro's advantage is update cadence (every 5 weeks vs every 20 months). On price, ads, in-app purchases and device support there is nothing between them.
